Yon cannot "stop" your mind from doing anything. In fact, if you try it usually makes you obsess about the very thing you are trying to avoid.
You can, however, START thinking about something else more positive. And eventually that new thought process will shove the bad thoughts out the door. It's a concept I heard on an anxiety podcast once and it really can work.
